Kasama fire, 3 September 2022 Kasama, Shiwang'Andu
The fire started on 3 September 2022 in Kasama, Zambia, and satellites saw it burning for 18 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 5,510 hectares from heat detections, spread across 2 municipalities.
It is the 211th largest in Northern since 2016 (of 628 with a page). Number 89 in Zambia in 2022, of 235.

Fire radiative power detected each day, in megawatts, and number of hotspots. The magenta bar marks the peak day.
The weather it burned in
It had gone more than two months without rain (1 mm or more) when it started.
This area had burned before
96% of the perimeter overlaps earlier fires recorded since 2016: 3,936 ha in 2016, 4,129 ha in 2017, 1,104 ha in 2018, 2,583 ha in 2019, 3,903 ha in 2020, 1,442 ha in 2021. Part of it burned more than once, so the yearly figures add up to more than the 5,273 ha that had burned before.

Burnt area inside each municipality, from crossing the GWIS perimeter with administrative boundaries. The distance runs from the point marking the centre of each area to the nearest fire: staying a kilometre away does not mean it reached the houses.
People and buildings inside the perimeter
GHSL 2020Inside the perimeter there were about 4.7 hectares of built-up land and about 300 residents (GHSL 2020, satellite-based estimate).
This is an estimate on 100 m cells, made from satellite imagery and census data: it does not mean that homes burned or that anyone was harmed. The perimeter also contains land that never burned.

The smoke
CAMS · CopernicusOn 10 September 2022 the air beside the fire reached 121 µg/m³ of PM2.5. That day averaged 43: 2.9 times the WHO daily guideline (15).

Frequently asked questions
- How long did the Kasama fire last?
- According to the heat detections seen by satellite inside the perimeter, it burned from 3 September 2022 to 20 September 2022 (18 days). The perimeter dates it from 6 September 2022 to 14 September 2022.
- How much area did it burn?
- The perimeter GWIS (Copernicus) rebuilt from heat detections is 5,510 hectares (55.1 km²). It is an estimate: official national figures may differ.
- Which municipalities burned?
- The fire entered 2 municipalities: Kasama (4,088 ha, 0.4 %); Shiwang'Andu (1,460 ha, 0.2 %).
- What was the weather like?
- During the fire the temperature reached 31.0 °C, humidity dropped to 17 % and gusts hit 49 km/h. The fire danger index (FWI) reached 51, class Extreme.
- Where does this data come from?
- From the GWIS (Copernicus) burnt perimeter, NASA FIRMS VIIRS hotspots and the administrative boundaries of Zambia (geoBoundaries). It is not an official report.
Where to verify it
A satellite detection is not an official report. Final figures and the fire’s status are published by each country’s emergency service.

Does something look wrong on this page?
This page is built from satellite data and official records, and it sometimes gets things wrong: the wrong dates, the wrong town, two fires merged into one, or something that was not a wildfire at all. If you know this fire first-hand (you live nearby, saw it, fought it or reported on it), tell us what really happened and we will check it.

How we know this
- Perimeter: GWIS (Copernicus), rebuilt from heat detections rather than mapped on imagery.
- Dates adjusted with the VIIRS detections inside the perimeter, which said 6 September 2022 to 14 September 2022. 231 Suomi-NPP VIIRS detections on those dates.
- We have not matched this page with any official record.
- Weather: Copernicus ERA5 reanalysis at the fire location, in cells of about 25 km.
- Built-up area and population come from the JRC Global Human Settlement Layer (epoch 2020, 100 m cells), summed inside the perimeter: an estimate of what was there, not a damage count.
Where this data comes from
The perimeter comes from the Copernicus Global Wildfire Information System (GWIS), which rebuilds it from MODIS and VIIRS heat detections and publishes it under CC BY 4.0. It is not measured on imagery as in Europe, so it is an estimate. Heat detections come from the VIIRS sensors aboard Suomi-NPP and NOAA-20, distributed by NASA FIRMS at 375 m resolution. Municipal boundaries come from geoBoundaries ADM2 (Creative Commons Attribution 4.0 (CC BY 4.0)). The area per municipality is computed by WorldFires by crossing the perimeter with those boundaries, so it may differ from each country’s official figure.
